Hi there, I have a serious problem regarding the network connectivity in virtual PC. Here it goes.... I have installed Microsoft Virtual PC in my computer. Then, I have installed 2 OS (Server 2003 as Server, Server 2003 as member server). then i have created a loop back adapter in both of the OS. I would like to know that if I can ping the nics from different virtual PC os, how to configure the connectivity? Do I need to enable NAT in all the Virtual machines or in the host computer? Please do help me in this regard. Thank you.
